BufferedStream.EndWrite(IAsyncResult) Method
Definition
Important
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Ends an asynchronous write operation and blocks until the I/O operation is complete. (Consider using WriteAsync(Byte[], Int32, Int32, CancellationToken) instead.)
public:
override void EndWrite(IAsyncResult ^ asyncResult);
public override void EndWrite (IAsyncResult asyncResult);
override this.EndWrite : IAsyncResult -> unit
Public Overrides Sub EndWrite (asyncResult As IAsyncResult)
Parameters
- asyncResult
- IAsyncResult
The pending asynchronous request.
Exceptions
asyncResult
is null
.
This IAsyncResult object was not created by calling BeginWrite(Byte[], Int32, Int32, AsyncCallback, Object) on this class.
Remarks
In the .NET Framework 4 and earlier versions, you have to use methods such as BeginWrite and EndWrite to implement asynchronous file operations. These methods are still available in the .NET Framework 4.5 to support legacy code; however, the new async methods, such as ReadAsync, WriteAsync, and FlushAsync, help you implement asynchronous file operations more easily.
EndWrite must be called exactly once for every call to BeginRead. Failing to end a read process before beginning another read operation can cause deadlock or other undesirable behavior.
